Specification of Letters Patent.

Patented Jan. 26, 1909.

Application :filed March 2, 1908. Serial No. 418,843.

To all whom it may concern:

Beit known that l, CHARLES W. ILLARS, a citizen of the United States, residing at Ottawa, in the county ofFranklin and State of Kansas, have invented certain new and useful Improvements in Jewelers Tools, of which the following is a specification, reference being had to the accompanying drawings.

My invention :relates to improvements in jewelers or watch makers7 tools and more particularly to a ruby pin setter.

The object of the invention is to provide a tool of this character by means of which a ruby jewel pin may be set without removing,

the hair spring and roller table frornthe balance wheel stad, thereby not disturbingthe regulation of the watch and not drawing the temperfrom the staif and pivots ofthe bal-A ance wheel.

Withthe above and other objects in view, the invention consists of the novel features of construction and the combination andl arrangement of arts hereinafter fully described and claimed, and illustrated inthe accompanying drawings, in which- Figure 1 is a perspective view of my improved jewel pin setter; Fig. 2 is an inverted plan view of the same showing a balance wheel in position upon the device; and

Fig. 3 is a detail transverse Section taken on the plane indicated by the line 3--3 in Fig. 2.

My improved tool comprises two converging resilient or spring jaws 1, 2 having their top faces 3 flat and disposed in the same longitudinal plane and their bottom and inner faces 4 inclined upwardly and inwardly to the top faces 3 so that said blades have their inner portions tapered or beveled to an'ledge 5 which is V-shaped in cross section, as

40 clearly shown inFig. 3. The jawsv 1, 2 are united at their converging ends to provide aV portion 6 adapted to be placed in the flame of a lamp or other heater and upon the opposite end of one of said jaws may be arranged a suitable handle 7 which will enable the tool to be conveniently manipulated and protect the o erators hand from the heat'of the jaw. Said jaws 1, 2 are preferably formed from a single piece of copper yor other metallicfwire by shaping one of its ends to provide the converging upper and lower faces 3, 4l of the jaws and' by then bending the portion thus shaped upon itself to provide the end 6.

1n use, the balance wheel is placed upon the fiat top faces 3 of the jaws and is then 55 moved toward the outer end 6 of the tool so that the inner beveled edges 5 of the jaws will wedge between the roller table and the crosspiece of the balance wheel, as clearly shown in 1Eig. 3. Vit will be Seen that by 60 means of the tool, a roller jewel or ruby pin can be set without removing the hair spring and roller table from the balance wheel staff, thereby not disturbing the regulation of the Vwatch and not drawing the temper from the Stai and pivots of the balance wheel staif. The peculiar construction of the tool allows just suiiicient heat to be carried from the flame ofthe lamp to the roller table to melt the Shellac with which the ruby pin is fas- 7o tened', thus enabling the workman to set the Aroller jewel or ruby pin perfectly straight before the shellac becomes cold and sets. By means of the tool, a loose roller jewel or ruby pin may be reset 1n a few minutes without 75 disturbing the table or hair spring, since the small amount of heat carried y the jaws will not be sufficient to injure said parts.

rihe tool may be used for slightly annealing the pivots of the balance sta' so that they 80 can be straightened without danger of breaking them.

Having thus described my invention what I claim is:

1. A tool of the character described comprising a jaw, a handle at one end of the latter,v a second jaw disposed angularly with respect to the first mentioned one, said jaws being united at their converging ends to provide a projection adapted to be heated, the opposing or inner edges of said jaws being beveled, substantially as described.

2. A tool of the character described comprising a handle and a metallic body formed from a piece of resilient wire having one end attached to the handle and its other end bent uponitself to rovide converging jaws, said jaws having at upper faces and inwardly and upwardly inclined bottom faces, said faces providing said jaws with inner edges of tl-shape in o ljoes section, substantially es de: inner edges and a handle upon the l'iee or dllt scribed. verging end of one of Said jews.

3. A tool of the character described oom: In testimony whereof I hereunto alix 1113' prsing eJ metallic body fori-ned fromI a piece signature in the presence oi' two witnesses. 5 of Wire by bending the same upon itself to CHAKLES YV. PILLAKS.

rovide the projection 6 adapted to be Vfitnesses:
